Trait ReadOnlyQueryData

Source 
pub unsafe trait ReadOnlyQueryData: QueryData<ReadOnly = Self> { }
Expand description

A QueryData that is read only.

§Safety

This must only be implemented for read-only QueryData’s.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
